According to documents revealed by San Francisco Chronicle, the Google’s mystery barge taking shape in San Francisco Bay will eventually be a 50-foot-tall, 250-foot-long structure made of recycled shipping containers and fish fins resembling sails. According to these documents the barge is intended as a “studio” and “temporary technology exhibit space” that will drive tourism along the waterfront. By and Large is assumed to be connected with Google, given that the company acknowledged this week that is planning to use its barges to showcase new technologies.

The striking glass-and-steel design shown in an artist’s rendering looks similar to the structure raised by Google Last week. According to documents, the barge will be able to host up to 1,000 visitors a day during month long residencies. Locations proposed so far include Fort Mason, along with Angel Island, Redwood City, and Rosie the Riveter Historical National Park in Richmond. Eventually it will sail to San Diego and other West Coast ports, according to the Chronicle.
